WitrynaSodium methanethiolate or sodium thiomethoxide (CH 3 SNa, MeSNa) is the sodium conjugate base of methanethiol. This compound is commercially available as a white solid. It is a powerful nucleophile that can be used to prepare methylthioethers. Its hydrolysis in moist air produces methanethiol, which has a low odor threshold and a … WitrynaReactions. Sodium ethoxide is commonly used as a base in the Claisen condensation and malonic ester synthesis. Sodium ethoxide may either deprotonate the α-position of an ester molecule, forming an enolate, or the ester molecule may undergo a nucleophilic substitution called transesterification.If the starting material is an ethyl ester, trans …
